“The greatest problem with the double tap is that you don’t know where the **** your second shot is going, since it wasn’t aimed.”
Stopped reading. Author is an idiot.
Affirmative. When I was on the police department, our standard range course included double-tap to the chest, then one to the head. If the threat ended before we got to the head shot, we could presume he either wasn't wearing body armor, or it wasn't effective. If he was still standing after a double-tap to the chest, that head shot was automatically on the way thanks to muscle memory.
We all consistently placed both shots of the double-tap right at center mass, because we were trained to immediately regain sight picture after the very first shot. In practice, it seemed like I never lost sight picture at all, it was so ingrained by training.
